PACKING DEVICE.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed January 30, 1914, Serial No. 815,383. Renewed May 3, 1918. Serial No. 232,384.

To all whom it may concern:

Be it known that I, LoUIs H. MARTELL, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented a certain new and useful Improvement in Packing Devices, of which the following is a full, clear, and exact description.

This invention relates to a device for packing a pump plunger. In the particular form of the device herein illustrated, it is applied to packing a plunger extending between opposed cylinders offa pump.

The object of the invention is to provide a device which will effectively prevent the seepage of water or other fluid material along the plunger, as it reciprocates.

In general, the invention comprises the elements and their combinations as defined by the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this specification, .in which Figure l is a side elevation with portions in section; Fig. 2 is a sectional elevation on the line 22 of Fig. 1; Fig. 3 is an elevation-with portions in section of a modified form of my device; and Fig. 4 is a section along the line 44 of Fig. 8. The opposing cylinders of a pump are indicated at 1 and 2, and the plunger which extendsbetween the cylinders of the pump is indicatedat 3. Thecylinder head 1 is recessed, and is adapted to receive a sleeve 4, which has an easy fit in the recess. This cylinder contains a packing 4, which engages with the piston rod. At its forward end, the'sleeve 4 is beveled.

Ahead of the'sleeve 4 is a sleeve 5, which at its inner end is beveled, thereby forming a groove between the sleeves 4 and 5. In this groove is a packing 6, which lies against the surface of the recess formed in the head 1, the packing 6 being compressed as the sleeve 5 is moved toward the sleeve 4.

The sleeve 5 isprovided with a flange 7 at its forward end, whichis provided with two. series of threaded openings, the function of which will be stated a little later on.

The cylinder head 2 is recessed in a manner similar to that described with respect to cylinder 1, and receives a sleeve 8, packing 9, in exactly the same manner as that heretofore described with respect to the sleeve 4. p p

A sleeve 10 havingits inner end beveled,

engages the packing 9, to compress the same in the same manner as does the inner end of the sleeve 5. Between the plunger and the sleeve 10 is a packing 11 v The sleeve 10 is provided with an extending portion 12, which is ofproper diameter to fit within a recessed portion 13 0f the sleeve 5,the fit between the extending portion 12 and the sleeve 5 being such that the sleeves 5 and 10 may be readily moved relatively to each other.

Uponthe extending portion 12 of sleeve 10 there is a compressing member 14, the diameter of which is such as to readily slide within a recessed portion 15 ofsleeve 5. Ahead of the compressor member 14 is packing 16 which is adapted to be compressed, as the compressor member 14 is moved toward the sleeve 5.

The compressor member 14 has a flanged head 17 through which extend a plurality of threaded bolts 18, the said bolts extend-v ing into certain of the threaded openings in the head 7 of the sleeve 5. Manipulation of these bolts 18 draws the compression member 17 toward the sleeve 5, and thereby compresses the packing 16.

The sleeve 10 is provided with a head 10*, and between the head 10 and the head 'I' there extends threaded bolts 19, these bolts engaging with certain of the threaded open? ings in the head'7, while the heads of the bolts engage with the head 10 The bolts 19 pass through the openings 20, which are formed with the head 17 of the compressor member. I

Adjustment of the bolts 19 will cause the sleeves 5 and 10 to move away from each other, thereby compressing the packing 6 and 9, which is carried adjacent the sleeves 4 and 8 respectively. i

It will be seen from the foregoing description that it will be impossible for any liquid to pass between the packing and plunger, as it reciprocates. The packing 6 and 9, together with the packing 15 may be suitably compressed by the manipulation of the bolts 18 and 19, so as to tightly seal all possible sources of exit for the fluid.

In Figs. 3 and 4, there is shown a slightly modified form of the device of my invention.

7 In these figures, the heads of the opposing cylinders are indicated at 20 and 21. These cylinders are recessed. IVithin the recess of the cylinder head-21 there extends a-sleeve 22, which at its inner end isprovided with a beveled portion that engages with a packing 23. The packing also engages the end and outer side of the recess in the cylinder 21 so that as the sleeve 22 is moved inwardly the packing 23 will be compressed.

The sleeve 22 is formed to havea sliding fit in'the recess of the head of the cylinder 21, and also to have a sliding fit upon the piston 3. The sleeve 22 is provided with water grooves 22 The cylinder head is provided with a groove which receives a sleeve 24 and packing 25 that operates in the same manner as that just described with respect to sleeve 22. The sleeves 22 and 24 extend slightly beyond the face of their respective cylinders. Sleeve 22 coeperates with a sleeve 26. The

' engaging faces of these sleeves have a groundfit, thereby preventing the escape of any fluid between them.

This sleeve 26 is provided with a recessed portion 26 and with a head 27 which contains two sets of screw threaded openings.

Asleeve' 28 extends along the plunger 3, and has within it a packing sleeve 29. The. sleeve 28 is provided with a head 30. The sleeve 28 extends within'the recessed portion 26 of the sleeve 26, and at its inpressing member 33 has a head 33 with which coijperates bolts 34 which are adapted to engage with certain of the screw threaded openings in thehead 27. 'These bolts when tightened, draw the compressor member toward the head 27 and thereby compress the packing 32.

Between the head 30 and the sleeve 24 is a two-part sleeve 35 containing suitable packing, the parts of the sleeve being held together by a bolt 36. The engaging faces of the sleeves 24 and 35, as well as the engaging faces of the sleeve 35 and the head 30, are ground to fit, thereby preventing the escape of fluid from the plunger 3. Y Y

'Bolts,-one of which is indicated at 37, engage in certain, of the threaded openings in the head 27 and at their opposite ends bear against the head 30. These bolts extend through slotted openings 38 in the head 33 of the compressor member. Manipulation of the bolts 37 will cause the heads 27 and30 to be pushed apart, thereby compressing the packing 23 and .25 to form a seal to prevent the escape of fiuid at these points, and the packing 32'will effectively prevent the escape of fluid between the sleeves 28 and 26.

Having thus described 7 my invention,

what I claim is:
